Application April 18, 1951, Serial No. 221,692 4 Claims. Cl. 250-51 This invention relates generally to a sterilizing apparatus and particularly to a sterilizer for drinking glasses.

The main object of this invention is to provide a means for completely sterilizing glasses used in drinking and eating places.

The second object is to perform the sterilizing operation without any additional labor or loss of time on the part of the operator. I

We accomplish these and other objects in the manner set forth in the following specification as illustrated in the accompanying drawings, in which I Fig. 1 is a perspective view of the device.

Fig. 2 is a transverse vertical section taken along the line 2-2 in Fig. 1.

Fig. 3 is a fragmentary section taken along the line 3-3 in Fig. 2.

Fig. 4 is a fragmentary perspective view of one of the ultra violet tubes used in the device.

Referring in detail to the drawing there is shown a cabinet including a back 10, the ends 11, a front 12 containing the transparency 13, and a top frame 14 surrounding and supporting a screen table 15. The frame 14 rests upon the cleats 16 which are secured to the members 10, 11 and 12.

Between the ends 11 are mounted the reflectors 17 and 18 which are supported by the blocks 19 which are secured to the ends 11. The reflector 17 is concave on its under side and the reflector 18 is convex on its upper side. On each block 19 is mounted a tube supporting bracket 20, between whichis supported the horizontal ultra violet tube 21 to which current is supplied by a transformer 22 through the leads 23 and 24.

2,738,428 Patented Mar. 13, 1956 ice sufiiciently larger dimensions than said lamp to shield said lamp from dripping water, a convex reflector mounted under said lamp having the same width as said concave Current is supplied to the transformer 22 through the flexible cord 25.

Supported by the cleats 16 are the reflectors 26 which extend almost to the lower edges 27 of the reflector 18.

An auxiliary lamp 28 is placed behind the transparency 13 and its leads are either directly connected to the transformer 22 or interconnected with the main tube 21 as an indicator showing whether or not the sterilizer tube 21 is operating.

In use, drinking glasses 29 are placed inverted on the screen table 15 and power turned on the tube 21. Rays emitted by the tube 21 are reflected upwardly over the entire area of the screen 15, thereby subjecting the glasses to the sterilizing action. Not only is work saved but the sterilizing action is complete and the entire cabinet and the supported glasses 29 are given a unique appearance which enhances its value as an advertising device.

reflector, upturned concave reflectors mounted along each side of said cabinet, said last reflectors having lower edges adjacent but spaced from the lower edges of said convex reflector, the front of said cabinet having a transparency therein and an auxiliary lamp behind said transparency for indicating the operability of said ultra violet lamp.

2. A sterilizer for drinking glasses comprising a rectangular cabinet having a wire cloth top for supporting the glasses, an elongated ultra violet lamp extending longitudinally of said cabinet below said top and intermediate the sides of the cabinet, an inverted channel shaped concave reflector mounted over said lamp beneath said top, said reflector having sufliciently larger dimensions than said lamp to shield said lamp from dripping water, a convex reflector of similar shape and dimensions mounted under said lamp, and longitudinal channel shaped concave reflectors extending along opposite sides of the cabinet, said last reflectors having upper edges approximately 'at the top corners of the cabinet and lower edges adjacent upper edge approximately at a top corner of the cabinet and a lower edge adjacent but spaced from a lower edge of said convex reflector. 1

4. A sterilizer for drinking glasses comprising a cabinet having a wire cloth top for supporting the glasses, an ultra violet lamp mounted centrally in said cabinet, a concave reflector over said lamp and beneath said top having down-turned edges, said reflector having sufliciently larger dimensions than said lamp to shield said lamp from dripping water, and upwardly facing concave reflector ,means disposed laterally on opposite sides of said lamp,

said reflector means having an upper edge approximately at atop corner of the cabinet and extending downwardly toward the center of the cabinet to a lower edge portion defining a central bottom opening in said reflector means.
